             Summary: Encounter an exception that contains "max key length 
exceeded ..."  when reporting metrics to influxdb
                 Key: FLINK-21747
                 URL: https://issues.apache.org/jira/browse/FLINK-21747
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Metrics
    Affects Versions: 1.10.0
            Reporter: tim yu


I run a stream job with insert statement whose size is too long, it report 
metrics to influxdb. I find many influxdb exceptions that contains "max key 
length exceeded ..." in the log file of job manager . The job could not write 
the metrics to the influxdb, because "task_name" and "operator_name" is too 
long.
